The one thing that the public dislike is novelty. Any attempt to extend the subject matter of art is extremely distasteful to the public; and yet the vitality and progress of art depend in a large measure on the continual extension of subject-matter. The public dislike novelty because they are afraid of it. It represents to them a mode of Individualism, an assertion on the part of the artist that he selects his own subject, and treats it as he chooses.
